What is ganache?
Ganache is a basic pastry component made from a mixture of melted chocolate and cream, and used as a velvety smooth chocolate filling, sauce or frosting. It can be made to different consistencies by altering the ratio of cream to chocolate. It has various uses, from glazing a statement cake, to making chocolate truffles.
Ganache is made with a mixture of chocolate and cream, whisked together to create a rich, chocolatey emulsion. These two ingredients are all you need for a basic ganache, although sometimes mascarpone is added for a creamier texture.
